Some interesting aspects of total disintegration of heavy emulsion nuclei at high energies

Abstract

Analysis of the events having Nh ≥ 28 produced in 50 GeV pion (π)−–Em and 400 GeV proton (p)–Em interactions and the results obtained at different incident energies reveal that the probability of total disintegration of the target nuclei and the value of [Formula: see text] strongly depend on the mass of the incident particle as well as the target nuclei. This probability is observed to be independent of the energy of the projectile in p–Em reactions but not in π−–Em collisions. The mean normalized multiplicity, R4, calculated in terms of the created charged particles, is independent of the identity and energy of the impinging hadron beyond ~20 Gev. Furthermore, the values of [Formula: see text] and [Formula: see text] are observed to depend weakly on the energy of the projectile. The maximum number of charged particles constituting a cluster is observed to be four at both incident energies; the characteristics of clusters are observed to be independent of the nature and energy of the impinging hadron.
